At least they have a system that works for them and each pipe can be identified, I had not heard about these purple pipes before. In my country everything is chaotic, there is no identification of pipes and very little is done to purify the water, although we have many wells, lakes and so many places where the water can come out they usually do rationing and it is because they do not give due maintenance to the pipes
